The Fragmented IoT Data Challenge
The rapid development of the Industrial Internet of Things (IIoT) has led to an explosion of fragmented, diverse data across countless devices. Managing access control for this data is a major challenge, as existing encryption schemes struggle to offer detailed access control, low-cost operations, and efficient storage simultaneously. Traditional trusted-server models are no longer sufficient due to increasing cyber threats and scalability issues.
Current Attribute-Based Searchable Encryption (ABSE) schemes face significant hurdles in IoT environments, often requiring double encryption leading to high computational overhead and excessive ciphertext sizes. Furthermore, many only support limited access structures, making complex policy design impossible.
LWABSE: An IoT-Oriented ABSE Scheme
Our proposed LWABSE scheme directly addresses the shortcomings of existing solutions. It innovatively maps relationships between data keywords and user attributes to access rules, leveraging a bilinear map for cryptographic operations. This allows data owners to define complex access structures using circuit encoding rules, ensuring that only users whose attribute tags precisely match the policy can search and decrypt data.
The scheme is optimized for IoT characteristics, performing efficiently with small data sizes, across large-scale systems, and accommodating diverse data types. It ensures message confidentiality, authenticity, and bilateral access control, making it a robust solution for secure IoT data sharing while protecting user privacy.
Demonstrated Efficiency & Superiority
Through comprehensive experiments, our LWABSE scheme demonstrated superior performance compared to classical evidence encryption schemes. Specifically, it exhibits higher encryption/search efficiency and enhanced access control capabilities in handling IoT data.
The scheme significantly outperforms others in search algorithm speed and keyword encryption efficiency. Unlike some existing methods, our solution is robust against keyword guessing attacks and supports dynamic keyword sizes, offering greater flexibility and security in practical IoT deployments.
Robust Security Based on DBDH Assumption
The security of the LWABSE scheme is rigorously proven to be selectively secure under the Decisional Bilinear Diffie-Hellman (DBDH) assumption. This foundational cryptographic assumption ensures that an adversary with polynomial time capabilities has at most a negligible advantage in compromising the system's security.
The design guarantees that data owners can formulate complex access structures, encrypt data, and upload it securely. Data users whose attributes satisfy the access structure can reliably search, download ciphertext, and decrypt it offline to obtain plaintext, even against adaptive adversaries in a chosen-keyword attack game.

Enhanced Privacy & Scalability for IIoT
The LWABSE scheme is uniquely designed to handle the diverse and fragmented nature of Industrial IoT data. By utilizing innovative circuit encoding rules and a bilinear map implementation, it achieves both granular access control and efficient data handling. This makes it ideal for environments where data integrity and user privacy are paramount, especially across large-scale, multi-user, and multi-device deployments.
From medical services to environmental monitoring, our solution ensures data remains secure and accessible only to authorized users, dramatically improving the utility and trust in IIoT applications.
